For computers engines and Human Chess Championhip

[Chessqueen]

This apply for for computer engines where we believe that Human GMs can come out with better Opening after move 6, but this apply more for top Human Chess Championship the 2 strongest Chess Players of their times believe that the classical chess requires too much preparation and most games are cooked up to moves 28 specially with computers, even GM Bobby Fisher was thinking this way when he quit at the same age 32 of GM Carlsen in his prime.

NOTE: A suggestion to eliminate 28 prepared moves in World Chess Championship is to give both players the opening that they will play up to only 6 moves, and they can place up to 40 openings in a bowl for them to select.
